Tried reboot and even re-install of EN. Still same problem. I attached another snapshot showing that I have 2 notebooks that show that I am sharing (bleu people icon) but I am still unable to manage any sharing properties and the person invited is unable to connect.

Hi all, I am using Evernote windows based client and have purchase the PREMIUM version. I am having a problem with sharing a notebook with another user. The user received the email and when he tries to connect or view the folder he receives this error message: " Shared notebook assigned to another account This shared notebook is assigned to another user. Contact the notebook owner to obtain an invitation." And when I try to unshare the notebook I do not see any option when I click the share note option: see attached photo. Any help would be greatly appreciated.
